Class Ranking Outdated?

Check out the Tribune Class rankings outdated? Naperville schools say yes. Check out this amazing fact:

But at intensely competitive Naperville Central High School, Johnston's 3.9 grade-point average on a 4.0 scale ranks somewhere around 140th in a class of 800.

Since late undergraduate I have always been a fan of pass/fail (w/ optional honors). Someday I will open a college and do things right.
